Scooby's Laff-A Lympics (1977)

Season 1: Episode 9

B.F. manages to release himself and reprogram Dog Wonder so he won't obey Beastwoman's Beastwhistle. B.W., meanwhile, employs some bird to seed the clouds and have them rain on the seeded Big City, turning it into a jungle. The Daring Duo learn she plans to do this to the rest of the U.S.A. via rocket power, so Blue Falcon detains Beastwoman whilst Dynomutt goes up with the rocket which crashes into the lake and D.W. becomes a moss-covered mechanical mutt. Blue Falcon severs Beastwoman's powers by snipping her veins, and Big City is restored to normal. Blue Falcon attempts to shear Dynomutt's veins, but the latter decides to shake them off by dancing the Hula.
